Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The integrated server of the ZGR TPS200 NG on its 2.00 firmware version and 1.01 hardware version, allows a remote attacker to perform actions with the permissions of a victim user. For this to happen, the victim user has to have an active session and triggers the malicious request.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The ZGR TPS200 NG integrated server on firmware 2.00/hardware 1.01 contains a vulnerability that allows a remote attacker to execute actions with the permissions of an authenticated victim user. The attack requires the victim to have an active session and be induced to trigger a malicious request, indicating a likely CSRF or session handling flaw in the web interface.

MitigationImplement anti-CSRF tokens and robust session validation in the integrated server, and update firmware if a patch is available from the vendor.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the device web interface or check device labeling; look for 'ZGR TPS200 NG', 'Zigor Zgr Tps200 Ng', or 'TPS200 NG' in the product name, header, or status page
    Affected if The device is a ZGR TPS200 NG integrated server
  2. Verify firmware version
    Log into the web interface and navigate to System Information, Status, or About page; check for firmware version display
    Affected if Firmware version is exactly 2.00
  3. Confirm web interface accessibility
    Attempt HTTP/HTTPS access to the device IP on common ports (80, 443, 8080); verify the login page or authentication prompt is reachable
    Affected if The web interface is accessible and accepts user authentication
  4. Check for anti-CSRF protections
    Inspect the HTML source of web forms (login, settings, configuration); look for hidden token fields with names like 'csrf', 'token', 'nonce', or 'xsrf'; check if forms submit without any token
    Affected if Forms in the web interface lack anti-CSRF token parameters or hidden fields

A user is affected if they have a ZGR TPS200 NG device running firmware 2.00 with an accessible web interface that does not implement anti-CSRF tokens in its forms.
